Background
Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined.
Methods
This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months.
Conclusion
This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

Background
Dipeptidyl peptidase-4 (DPP4) inhibitors are frequently prescribed for patients with type 2 diabetes; however, their cost can pose a significant barrier for those with impaired kidney function. This study aimed to estimate the economic benefits of substituting non-renal dose-adjusted (NRDA) DPP4 inhibitors with renal dose-adjusted (RDA) DPP4 inhibitors in patients with both impaired kidney function and type 2 diabetes.
Methods
This retrospective cohort study was conducted from January 1, 2012 to December 31, 2018, using data obtained from common data models of five medical centers in Korea. Model 1 applied the prescription pattern of participants with preserved kidney function to those with impaired kidney function. In contrast, model 2 replaced all NRDA DPP4 inhibitors with RDA DPP4 inhibitors, adjusting the doses of RDA DPP4 inhibitors based on individual kidney function. The primary outcome was the cost difference between the two models.
Results
In total, 67,964,996 prescription records were analyzed. NRDA DPP4 inhibitors were more frequently prescribed to patients with impaired kidney function than in those with preserved kidney function (25.7%, 51.3%, 64.3%, and 71.6% in patients with estimated glomerular filtration rates [eGFRs] of ≥60, <60, <45, and <30 mL/min/1.73 m2, respectively). When model 1 was applied, the cost savings per year were 7.6% for eGFR <60 mL/min/1.73 m2 and 30.4% for eGFR <30 mL/min/1.73 m2. According to model 2, 15.4% to 51.2% per year could be saved depending on kidney impairment severity.
Conclusion
Adjusting the doses of RDA DPP4 inhibitors based on individual kidney function could alleviate the economic burden associated with medical expenses.

Treatment patterns and preferences for patients with Graves’ disease (GD) vary across countries. In this study, we assessed the initial therapies and subsequent treatment modalities employed for GD in real-world clinical practice in Korea. We analyzed 452,001 patients with GD from 2004 to 2020, obtained from the Korean National Health Insurance Service database. Initial treatments included antithyroid drug (ATD) therapy (98% of cases), thyroidectomy (1.3%), and radioactive iodine (RAI) therapy (0.7%). The rates of initial treatment failure were 58.5% for ATDs, 21.3% for RAI, and 2.1% for thyroidectomy. Even among cases of ATD treatment failure or recurrence, the rates of RAI therapy remained low. Regarding initial treatment, the 5-year remission rate was 46.8% among patients administered ATDs versus 91.0% among recipients of RAI therapy; at 10 years, these rates were 59.2% and 94.0%, respectively. Our findings highlight a marked disparity in the use of RAI therapy in Korea compared to Western countries. Further research is required to understand the reasons for these differences in treatment patterns.

Background
Acromegaly leads to various skeletal complications, and fragility fractures are emerging as a new concern in patients with acromegaly. Therefore, this study investigated the risk of fractures in Korean patients with acromegaly.
Methods
We used the Korean nationwide claims database from 2009 to 2019. A total of 931 patients with acromegaly who had never used an osteoporosis drug before and were treated with surgery alone were selected as study participants, and a 1:29 ratio of 26,999 age- and sex-matched osteoporosis drug-naïve controls without acromegaly were randomly selected from the database.
Results
The mean age was 46.2 years, and 50.0% were male. During a median follow-up of 54.1 months, there was no difference in the risks of all, vertebral, and non-vertebral fractures between the acromegaly and control groups. However, hip fracture risk was significantly higher (hazard ratio [HR], 2.73; 95% confidence interval [CI], 1.32 to 5.65), and non-hip and non-vertebral fractures risk was significantly lower (HR, 0.40; 95% CI, 0.17 to 0.98) in patients with acromegaly than in controls; these results remained robust even after adjustment for socioeconomic status and baseline comorbidities. Age, type 2 diabetes mellitus, cardio-cerebrovascular disease, fracture history, recent use of acid-suppressant medication, psychotropic medication, and opioids were risk factors for all fractures in patients with acromegaly (all P<0.05).
Conclusion
Compared with controls, patients surgically treated for acromegaly had a higher risk of hip fractures. The risk factors for fracture in patients with acromegaly were consistent with widely accepted risk factors in the general population.

Background
We aimed to investigate the moderating effects of obesity, age, and sex on the association between sleep duration and the development of diabetes in Asians.
Methods
We analyzed data from a cohort of the Korean Genome and Epidemiology Study conducted from 2001 to 2020. After excluding shift workers and those with diabetes at baseline, 7,407 participants were stratified into three groups according to sleep duration: ≤5 hours/night, >5 to 7 hours/night (reference), and >7 hours/night. The Cox proportional hazards analyses were used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident type 2 diabetes mellitus (T2DM). Subgroup analyses were performed according to obesity, age, and sex.
Results
During 16 years of follow-up, 2,024 cases of T2DM were identified. Individuals who slept ≤5 h/night had a higher risk of incident diabetes than the reference group (HR, 1.17; 95% CI, 1.02 to 1.33). The subgroup analysis observed a valid interaction with sleep duration only for obesity. A higher risk of T2DM was observed in the ≤5 hours/night group in non-obese individuals, men, and those aged <60 years, and in the >7 hours/night group in obese individuals (HRs were 1.34 [95% CI, 1.11 to 1.61], 1.22 [95% CI, 1 to 1.49], and 1.18 [95% CI, 1.01 to 1.39], respectively).
Conclusion
This study confirmed the effect of sleep deprivation on the risk of T2DM throughout the 16-year follow-up period. This impact was confined to non-obese or young individuals and men. We observed a significant interaction between sleep duration and obesity.

Lifestyle is a critical aspect of diabetes management. We aimed to define a healthy lifestyle using objectively measured parameters obtained from a wearable activity tracker (Fitbit) in patients with type 2 diabetes. This prospective observational study included 24 patients (mean age, 46.8 years) with type 2 diabetes. Expectation–maximization clustering analysis produced two groups: A (n=9) and B (n=15). Group A had a higher daily step count, lower resting heart rate, longer sleep duration, and lower mean time differences in going to sleep and waking up than group B. A Shapley additive explanation summary analysis indicated that sleep-related factors were key elements for clustering. The mean hemoglobin A1c level was 0.3 percentage points lower at the end of follow-up in group A than in group B. Factors related to regular sleep patterns could be possible determinants of lifestyle clustering in patients with type 2 diabetes.

Background
Previous studies on the epidemiology and complications of congenital adrenal hyperplasia (CAH) were conducted in Western countries and in children/adolescents. We aimed to explore the epidemiology of CAH, as well as the risk of comorbidities and mortality, in a Korean nationwide case-control study.
Methods
CAH patients (n=2,840) were included between 2002 and 2017 from the National Health Insurance Service database and the Rare Intractable Disease program. CAH patients were compared, at a 1:10 ratio, with age-, sex-, and index year-matched controls (n=28,400).
Results
The point prevalence of CAH patients in Korea was 1 in 18,745 persons in 2017. The annual incidence rate declined between 2003 and 2017 from 3.25 to 0.41 per 100,000 persons. CAH patients were at elevated risk for cardiovascular disease (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.4 to 1.9), stroke (OR, 1.7; 95% CI, 1.3 to 2.0), diabetes mellitus (OR, 2.8; 95% CI, 2.6 to 3.1), dyslipidemia (OR, 2.4; 95% CI, 2.2 to 2.6), and psychiatric disorders (OR, 1.5; 95% CI, 1.3 to 1.6). Fracture risk increased in CAH patients aged over 40 years (OR, 1.4; 95% CI, 1.1 to 1.7). CAH patients were at higher risk of mortality than controls (hazard ratio, 1.6; 95% CI, 1.3 to 2.0).
Conclusion
Our nationwide study showed a recent decline in the incidence of CAH and an elevated risk for cardiovascular, metabolic, skeletal, and psychiatric disorders in CAH patients. Lifelong management for comorbidity risk is a crucial component of treating CAH patients.

Background
We investigated how 100-g oral glucose tolerance test (OGTT) results can be used to predict adverse pregnancy outcomes in gestational diabetes mellitus (GDM) patients.
Methods
We analyzed 1,059 pregnant women who completed the 100-g OGTT between 24 and 28 weeks of gestation. We compared the risk of adverse pregnancy outcomes according to OGTT patterns by latent profile analysis (LPA), numbers to meet the OGTT criteria, and area under the curve (AUC) of the OGTT graph. Adverse pregnancy outcomes were defined as a composite of preterm birth, macrosomia, large for gestational age, low APGAR score at 1 minute, and pregnancy-induced hypertension.
Results
Overall, 257 participants were diagnosed with GDM, with a median age of 34 years. An LPA led to three different clusters of OGTT patterns; however, there were no significant associations between the clusters and adverse pregnancy outcomes after adjusting for confounders. Notwithstanding, the risk of adverse pregnancy outcome increased with an increase in number to meet the OGTT criteria (P for trend=0.011); odds ratios in a full adjustment model were 1.27 (95% confidence interval [CI], 0.72 to 2.23), 2.16 (95% CI, 1.21 to 3.85), and 2.32 (95% CI, 0.66 to 8.15) in those meeting the 2, 3, and 4 criteria, respectively. The AUCs of the OGTT curves also distinguished the patients at risk of adverse pregnancy outcomes; the larger the AUC, the higher the risk (P for trend=0.007).
Conclusion
The total number of abnormal values and calculated AUCs for the 100-g OGTT may facilitate tailored management of patients with GDM by predicting adverse pregnancy outcomes.

Background
To compare the renal effects of dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium-glucose cotransporter 2 (SGLT2) inhibitors on individual outcomes in patients with type 2 diabetes.
Methods
We searched electronic databases (MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials) from inception to June 2019 to identity eligible randomized controlled trials of DPP-4 inhibitors or SGLT2 inhibitors that reported at least one kidney outcome in patients with type 2 diabetes. Outcomes of interest were microalbuminuria, macroalbuminuria, worsening nephropathy, and end-stage kidney disease (ESKD). We performed an arm-based network meta-analysis using Bayesian methods and calculated absolute risks and rank probabilities of each treatment for the outcomes.
Results
Seventeen studies with 87,263 patients were included. SGLT2 inhibitors significantly lowered the risks of individual kidney outcomes, including microalbuminuria (odds ratio [OR], 0.64; 95% credible interval [CrI], 0.41 to 0.93), macroalbuminuria (OR, 0.48; 95% CrI, 0.24 to 0.72), worsening nephropathy (OR, 0.65; 95% CrI, 0.44 to 0.91), and ESKD (OR, 0.65; 95% CrI, 0.46 to 0.98) as compared with placebo. However, DPP-4 inhibitors did not lower the risks. SGLT2 inhibitors were considerably associated with higher absolute risk reductions in all kidney outcomes than DPP-4 inhibitors, although the benefits were statistically insignificant. The rank probabilities showed that SGLT2 inhibitors were better treatments for lowering the risk of albuminuria and ESKD than placebo or DPP-4 inhibitors.
Conclusion
SGLT2 inhibitors were superior to DPP-4 inhibitors in reducing the risk of albuminuria and ESKD in patients with type 2 diabetes.

Background
Thyroid cancer is becoming increasingly common worldwide, but little is known about the epidemiology of medullary thyroid carcinoma (MTC). This study investigated the current status of the incidence and treatment of MTC using Korean National Health Insurance Service (NHIS) data for the entire Korean population from 2004 to 2016.
Methods
This study included 1,790 MTC patients identified from the NHIS database.
Results
The age-standardized incidence rate showed a slightly decreasing or stationary trend during the period, from 0.25 per 100,000 persons in 2004 to 0.19 in 2016. The average proportion of MTC among all thyroid cancers was 0.5%. For initial surgical treatment, 65.4% of patients underwent total thyroidectomy. After surgery, external-beam radiation therapy (EBRT) was performed in 10% of patients, a proportion that increased from 6.7% in 2004 to 11.0% in 2016. Reoperations were performed in 2.7% of patients (n=49) at a median of 1.9 years of follow-up (interquartile range, 1.2 to 3.4). Since November 2015, 25 (1.4%) patients with MTC were prescribed vandetanib by December 2016.
Conclusion
The incidence of MTC decreased slightly with time, and the proportion of patients who underwent total thyroidectomy was about 65%. EBRT, reoperation, and tyrosine kinase inhibitor therapy are additional treatments after initial surgery for advanced MTC in Korea.

Background

Pheochromocytomas and paragangliomas (PPGLs) are rare endocrine tumors originating from chromaffin cells. PPGLs are associated with a high mortality rate and several complications. To date, no epidemiological studies have been conducted on PPGLs in Asia. This study aimed to investigate the epidemiology and prognosis of PPGLs in Korea using nationwide data.

Methods

Using the National Health Insurance Service Database, subjects with a principal diagnosis of PPGLs on two or more occasions between 2003 and 2014 who satisfied the operational definition of PPGLs were included. Incidence, prevalence, complications, metastasis, and mortality were investigated.

Results

In total, 1048 subjects with a mean age of 47.6±16.1 years were included. There was no sex preponderance. The overall prevalence of PPGLs was 2.13 per 100,000 persons, and the overall age-standardized incidence rate was 0.18 per 100,000 person-years. Malignant PPGLs accounted for 17.7% (185 of 1,048) of cases, and 94 subjects exhibited metastasis at the time of diagnosis. Among initially non-metastatic PPGLs, 9.5% (nine of 954) eventually metastasized after a mean duration of 78.1±41.4 months. The 5-year survival rates for non-metastatic and metastatic PPGLs at diagnosis were 97% and 84%, respectively. Multivariable Cox regression models adjusted for covariates showed that metastatic PPGLs were associated with a 2.40-fold higher risk of mortality than non-metastatic PPGLs (95% confidence interval, 1.38 to 4.17; P=0.002).

Conclusion

PPGLs are rare in Korea, and the prognosis of these endocrine tumors varies depending on whether they are benign or malignant. This epidemiological study paves the way for further research on PPGLs.

Background

To investigate the effects of dipeptidyl peptidase-4 (DPP-4) inhibitors on renal outcomes in patients with type 2 diabetes.

Methods

MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched to identify randomized controlled trials (RCTs) of DPP-4 inhibitors from inception to September 2017. We selected eligible RCTs comparing DPP-4 inhibitors with placebo or other antidiabetic agents and reporting at least one renal outcome. A meta-analysis was conducted to calculate standardized mean differences, weighted mean differences (WMDs), relative risks (RRs), and 95% confidence intervals (CIs) for each renal outcome.

Results

We included 23 RCTs with 19 publications involving 41,359 patients. Overall changes in urine albumin-to-creatinine ratio were comparable between DPP-4 inhibitors and controls (P=0.150). However, DPP-4 inhibitors were associated with significantly lower risk of incident microalbuminuria (RR, 0.89; 95% CI, 0.80 to 0.98; P=0.022) and macroalbuminuria (RR, 0.77; 95% CI, 0.61 to 0.97; P=0.027), as well as higher rates of regression of albuminuria (RR, 1.22; 95% CI, 1.10 to 1.35; P<0.001) compared with controls. Although DPP-4 inhibitors were associated with small but significantly lower estimated glomerular filtration rate (WMD, −1.11 mL/min/1.73 m2; 95% CI, −1.78 to −0.44; P=0.001), there was no difference in the risk of end-stage renal disease between two groups (RR, 0.93; 95% CI, 0.76 to 1.14; P=0.475).

Conclusion

DPP-4 inhibitors had beneficial renal effects mainly by reducing the risk of development or progression of albuminuria compared with placebo or other antidiabetic agents.

Background

Past decades of division have led to substantial differences in medical environments between South and North Korea. However, little is known about North Korea's medical status and research field, especially regarding endocrinology. In this study, we report the characteristics of North Korea's articles regarding endocrine-related diseases.

Methods

Among the nine medical journals, articles published in Internal Medicine between 2006 and 2015 were reviewed. A total of 2,092 articles were included; among them, 96 articles were associated with endocrinology. We analyzed these articles according to the disease categories they focused on and evaluated their features.

Results

Articles related to diabetes mellitus accounted for 55.2% (n=53) and those to thyroid disease accounted for 28.1% (n=27). Other disease categories, including adrenal gland (n=1), pituitary gland (n=1), and osteoporosis (n=3), comprised minor portions. Regarding diabetes mellitus, more than half the articles (n=33) focused on treatment and complications. Experimental studies were conducted with old hypoglycemic drugs or natural substances for the treatment of hyperglycemia. Regarding thyroid disease, articles related to hyperthyroidism were the most common (51.9%, n=14), followed by thyroid nodule/cancer (18.5%, n=5). Unique article features were short length, no figures, and less than five references.

Conclusion

North Korea's endocrinology articles mainly focused on diabetes mellitus and thyroid disease. Persistent studies have been carried out in North Korea with dedication despite the poor medical environment. We hope that this study will be the beginning of mutual medical exchange and collaboration between North and South Korea.

Background

Glycemic variability is associated with the development of diabetic complications through the activation of oxidative stress. This study aimed to evaluate the effects of a dipeptidyl peptidase 4 inhibitor, vildagliptin, or a thiazolidinedione, pioglitazone, on glycemic variability and oxidative stress in patients with type 2 diabetes.

Methods

In this open label, randomised, active-controlled, pilot trial, individuals who were inadequately controlled with metformin monotherapy were assigned to either vildagliptin (50 mg twice daily, n=17) or pioglitazone (15 mg once daily, n=14) treatment groups for 16 weeks. Glycemic variability was assessed by calculating the mean amplitude of glycemic excursions (MAGE), which was obtained from continuous glucose monitoring. Urinary 8-iso prostaglandin F2α, serum oxidised low density lipoprotein, and high-sensitivity C-reactive protein were used as markers of oxidative stress or inflammation.

Results

Both vildagliptin and pioglitazone significantly reduced glycated hemoglobin and mean plasma glucose levels during the 16-week treatment. Vildagliptin also significantly reduced the MAGE (from 93.8±38.0 to 70.8±19.2 mg/dL, P=0.046), and mean standard deviation of 24 hours glucose (from 38±17.3 to 27.7±6.9, P=0.026); however, pioglitazone did not, although the magnitude of decline was similar in both groups. Markers of oxidative stress or inflammation including urinary 8-iso prostaglandin F2α did not change after treatment in both groups.

Conclusion

In this 16-week treatment trial, vildagliptin, but not pioglitazone, reduced glycemic variability in individuals with type 2 diabetes who was inadequately controlled with metformin monotherapy, although a reduction of oxidative stress markers was not observed.

AbstractAbstract PDFPubReader   

A brown tumor is a benign fibrotic, erosive bony lesion caused by localized, rapid osteoclastic turnover, resulting from hyperparathyroidism. Although brown tumors are one of the most pathognomonic signs of primary hyperparathyroidism, they are rarely seen in clinical practice. In this report, we present a case of 20-year-old woman with recurrent fractures and bone pain. Plain digital radiographs of the affected bones revealed multiple erosive bone tumors, which were finally diagnosed as brown tumors associated with primary hyperparathyroidism due to a parathyroid adenoma. This case shows that multiple, and clinically severe form of brown tumors can even occur in young patients.

AbstractAbstract PDFPubReader   

Hypothyroid myopathy is observed frequently and the resolution of the clinical manifestations of myopathy following thyroid hormone replacement is well known. However, a specific subtype of hypothyroid myopathy, Hoffmann's syndrome, characterized by increased muscular mass (pseudohypertrophy), proximal muscle weakness, muscle stiffness and cramps, is rarely reported. Herein, we describe a 34-year-old male who presented with proximal muscle weakness and non-pitting edema of the lower extremities. He initially visited the neurology department where he was suspected of having polymyositis. Additional laboratory evaluation revealed profound autoimmune hypothyroidism and elevated muscle enzymes including creatine kinase. The patient was started on levothyroxine treatment and, subsequently, clinical symptoms and biochemical parameters resolved with the treatment. The present case highlights that hypothyroidism should be considered in the differential diagnosis of musculoskeletal symptoms even in the absence of overt manifestations of hypothyroidism. To our knowledge, this is the first case reported in Korea.

Radioactive iodine (RAI) therapy has been used as a treatment option for Graves' disease, and it has been widely accepted to be safe. On the other hand, some evidence suggests that RAI therapy is possibly associated with a small increased risk of thyroid cancer. Herein, we report a rare case of anaplastic thyroid carcinoma (ATC) associated with Graves' disease, following RAI treatment. A 42-year-old woman had been diagnosed with Graves' disease and although she was treated with an antithyroid drug, she remained in a hyperthyroid state, which led to two RAI treatments. More than 10 years later, the patient revisited our clinic due to hoarseness, dysphagia, and dyspnea, which had lasted for 2 months. Neck computed tomography suggested thyroid carcinoma and a lymph node biopsy showed metastatic papillary carcinoma. The patient underwent total thyroidectomy and was finally diagnosed as having an ATC. It is not clear if the occurrence of ATC reported here was influenced by the RAI therapy or alternatively, it may only represent the delayed recognition of a rare change in the natural history of Graves' disease. Nevertheless, this report is worthwhile since it presents a very rare case of ATC that occurred eleven years after the RAI therapy for Graves' disease.

AbstractAbstract PDF
Osteoporosis in young men is extremely rare. In this report, we demonstrate a rare case of multiple vertebral fractures discovered in a young man with Budd-Chiari syndrome without prior history of trauma. A 29-year-old man was diagnosed as Budd-Chiari syndrome 12 years ago and underwent a mesocaval shunt to relieve the hepatic vein obstruction and was on warfarin therapy. He suffered from low back pain and it was not relieved by analgesics. A T-L spine X-ray revealed multiple compression fractures and the z-score at lumbar spine was -3.7 which is below the expected range for that age. The patient was treated with calcium, vitamin D and bisphosphonate, and showed clinical improvement. This case highlights the importance of the investigation for secondary osteoporosis in young adults with an underlying disease that alters bone metabolism.

AbstractAbstract PDF
BACKGROUND
Thyroid function depends on ethnic and environmental factors. North Korean refugees have the same genetic background as South Koreans, but they have been exposed to different environments. This study examines the prevalence and pattern of thyroid disorders in North Korean women living in South Korea, focusing on subclinical hypothyroidism (SCH). METHODS: The intended sample was a total of 327 North Korean women residing in Seoul. Health questionnaires and medical examinations, including serum thyrotropin (thyroid stimulating hormone, TSH), free thyroxine, and thyroid autoantibodies, were conducted. RESULTS: The prevalence of SCH was 9.4%. In logistic regression analysis, smoking, menopause, length of stay in South Korea, body mass index, history of thyroid disease, and metabolic syndrome were not associated with the risk of SCH. Whereas, the positivity of autoantibodies were associated with a high risk for SCH (odds ratio [OR], 4.840; 95% confidence interval [CI], 1.80-13.017; P = 0.002), and age was associated with a low risk for SCH (OR, 0.94; 95% CI, 0.888-0.994; P = 0.031). The serum TSH levels also decreased with increasing age, and in particular, there was significant difference between 30-39 years, and over 60 years (2.33 +/- 1.51 microIU/mL vs. 1.54 +/- 0.73 microIU/mL, P = 0.028). CONCLUSION: In North Korean women, the positivity of autoantibodies was associated with a high risk for SCH. But interestingly, a younger age was associated with a high risk for SCH. Considering that they suffered from severe famine at the period of growth, and this led to malnutrition, their thyroid dysfunction might be associated with the peculiar environment that they experienced.

AbstractAbstract PDF
Scanning with whole-body 131I scintigraphy after surgery has been a valuable diagnostic modality in the surveillance of patients with differentiated thyroid cancer. Radioiodine uptake is rarely observed in non-lactating breast tissue, which mimics thyroid cancer metastasis. We now report a case of a 45-year-old female thyroid cancer patient who underwent radioiodine therapy, and in whom breast uptake of radioiodine was observed on a post-therapy whole body scan. Her serum prolactin level was elevated to 328 ng/mL at the time of the radioiodine uptake, and the hyperprolactinemia was induced by her antipsychotic medications. Six months after she discontinued that medication, her serum prolactin level was normalized to 12.6 ng/mL and breast uptake of iodine was no longer present in a follow-up whole body scan.

AbstractAbstract PDF
Intra-operative parathyroid hormone (IOPTH) assay is a useful tool to confirm complete excision of all hyper-functioning parathyroid gland tissue. In this report, we describe a case with successful localization of distant metastasis in a patient with parathyroid carcinoma using the IOPTH assay. A 53-year-old man presented to our clinic with a serum calcium level of 11.8 mg/dL and an intact PTH level of 233.3 pg/mL. He had been treated for parathyroid carcinoma eleven years ago. Two suspected metastatic lesions were detected on the chest computed tomography. Due to the vastly different surgical field necessary to excise each lesion, we preferentially removed only one lesion and we monitored the other remaining suspected lesion without resection via IOPTH assay. Six months later, the patient's serum calcium and intact PTH levels remained within their normal ranges. To the best of our knowledge, this is the first case to effectively utilize IOPTH assay for the management of metastatic parathyroid carcinoma.

AbstractAbstract PDF
Multiple endocrine neoplasia type 2A (MEN 2A) is an autosomal dominant syndrome characterized by the presence of medullary thyroid carcinoma, pheochromocytoma, and hyperparathyroidism. MEN 2A arises due to a germline missense mutation of the RET proto-oncogene. Specific RET mutation analysis has revolutionized the diagnosis and therapy of this disorder, and early thyroidectomy may have lowered the morbidity and mortality associated with these diseases. Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of ACTH outside of the pituitary gland; the most common causes are malignancies, but rarely adrenal pheochromocytoma may be the cause.

AbstractAbstract PDF
Persistent or recurrent primary hyperparathyroidism after initial parathyroid surgery occurs at rates of 1.5~10%. A single missed parathyroid adenoma accounts for the majority of persistent hyperparathyroidism, whereas metachronous parathyroid adenoma is a rare cause of recurrent hypercalcemia. We report a case of a 39-year-old female who presented with recurrent pancreatitis. She had symptoms of hyperparathyroidism such as hypercalcemia, hypophosphatemia, hypercalciuria, nephrocalcinosis, and osteoporosis. She had a 2-cm firm neck mass under the right submandibular area. She was diagnosed with primary hyperparathyroidism 22 years ago. At that time, the right upper and lower parathyroid glands were removed after exploration of all parathyroid glands, and a right upper parathyroid adenoma was diagnosed. Now, she had a second surgery to remove the right submandibular mass with intraoperative PTH monitoring, which was diagnosed as a parathyroid adenoma in an ectopic supernumerary parathyroid gland. Because of hungry bone syndrome, she received calcium carbonate replacement therapy and has no evidence of recurrence. Here, we report a recurrent parathyroid adenoma in the undescended, supernumerary parathyroid gland after a long interval from the initial surgery.

Fulminant type 1 diabetes is characterized by diabetes with an abrupt onset, severe metabolic acidosis at diagnosis, a low HbA1c level and negativity for islet cell-related autoantibodies, and this illness has been classified as type 1B diabetes by the WHO. The prevalence of this disease is higher in Japan than any other country and recently, there have been an increasing number of such case reports in Korea. Genetic factors and environmental factors such as virus infection and an immune mechanism have been suggested as the mechanism of the pathophysiology, but this remains to be clarified.

AbstractAbstract PDF
Prolactin-secreting adenomas are the most common pituitary tumors. Menstrual disturbances and infertility are the main complaints in women with prolactinoma. Dopaminergic agonists such as bromocriptine are well-established treatments for prolactinoma when pregnancy is desired. Pregnancy-related outcomes in macroprolactinoma are worse than those in microprolactinoma. In addition, symptomatic tumor expansion during pregnancy occurs in 30% of women with macroprolactinoma. Therefore, when women with macroprolactinoma are planning a pregnancy, serum prolactin level should be normalized and the tumor volume significantly reduced. On the other hand, a spontaneous regression of macroprolactinoma can occur after pregnancy. We report a case of macroprolactinoma showing significant tumor regression during repeated pregnancies and low dose bromocriptine treatment, with a literature review.

AbstractAbstract PDF
Graves' disease is an autoimmune disorder in which thyrotropin-stimulating hormone receptor antibodies stimulate the thyroid gland. Stress hormones such as catecholamine are known to play important roles in the pathogenesis of Graves' disease. Pheochromocytoma with Graves' disease is extremely rare, and no case has been reported within the Republic of Korea. However, according to previous studies conducted abroad, pheochromocytoma influences the pathogenesis of Graves' disease by producing excessive cathecholamine. In the present report, we describe a 65-year-old female patient with paroxysmal hypertension and rapidly progressive body weight loss who was diagnosed as having Graves'disease with pheochromocytoma.

AbstractAbstract PDF
Two cases of typical acromegaly with empty sella syndrome presented to our institution. In the natural course of untreated pituitary adenoma, empty sella syndrome may result from necrosis by infarction or from hemorrhage of the pituitary gland. In our patients, the secretion of growth hormone continued in spite of the existence of empty sella syndrome. In one case, we confirmed the hypersecretion of growth hormone from sella by jugular vein sampling. Medical therapy with somatostatin analogue was attempted because there was no obvious mass in the sella. After 6~12 months of treatment with long-acting release octreotide, clinical features in our patients were improved, and the level of growth hormone and IGF-1 were also normalized.

AbstractAbstract PDF
BACKGROUND
A number of recent clinical studies have reported marked target organ damages in patients with primary aldosteronism. The aim of this study was to compare the incidence of target organ damages in patients with primary aldosteronism (PA) and essential hypertension (EHT). METHODS: The clinical records of 41 PA patients, over a 20-year period, were retrospectively analyzed. The clinical characteristics and incidence of target organ damages of 33 of the patients in this group were compared with those of 66 patients with essential hypertension, directly matched for age, gender and mean blood pressure. 8 of the PA patients could not be matched with EHT patients for age, gender and mean blood pressure, so were excluded from the comparison. The patients with essential hypertension were sampled from patients who visited for the evaluation of hypertension. RESULTS: Ischemic heart diseases were found in 18.2 and 10.6% of patients with PA and EHT, respectively (P = 0.22). From echocardiograms, left ventricular hypertrophy was found in 93.3% and 61.4% of patients with PA and EHT, respectively (P = 0.017). The degrees of left ventricular hypertrophy were correlated with the levels of serum aldosterone, with an r value of 0.490 (P < 0.005). Cerebrovascular attack was found in 18.2% and 1.5% of patients with PA and EHT, respectively (P = 0.005). Hypertensive retinopathy was found in 50% and 33.3% of patients with PA and EHT (P = 0.255), and nephropathy was found in 42.4% and 25.8% of patients with PA and EHT, respectively (P = 0.074). CONCLUSION: Patients with primary aldosteronism had target organ damages more frequently than with those with essential hypertension, which was independent of blood pressure.

AbstractAbstract PDF
Sheehan's syndrome occurs as a result of ischemic pituitary necrosis due to severe postpartum hemorrhage. The manifestations of this clinical syndrome are most often caused by a deficiency in the hormones produced by the anterior pituitary gland, whereas the neurohypophysis is usually preserved but can be involved in severe cases that manifest as diabetes insipidus. This is a report of Sheehan's syndrome that manifested with diabetes insipidus as presenting symptom 2 month's after delivery. The patient suffered massive bleeding, so received a blood transfusion. A combined pituitary stimulation and water deprivation test revealed deficiencies of not only anterior pituitary hormones, such as growth hormone and prolactin, but also of anti-diuretic hormone. We report this case, with a review of the literature.

AbstractAbstract PDF
Primary hyperparathyroidism is the most frequent cause of hypercalcemia, and its prevalence is increasing due to the routine examination of serum calcium levels. Primary hyperparathyroidims is most commonly caused by an adenoma or hyperplasia of the parathyroid gland. A cystic parathyroid adenoma is an extremely rare cause of primary hyperparathyroidism. In our case, a-79-year old female presented with lower back pain and constipation. Her serum calcium, phosphate and immunoreactive parathyroid homone levels were 15.6, 1.8mg/dL and 371.8pg/mL, respectively. Neck CT revealed a cystic mass and a contour bulging heterogeneous mass in the left inferior right thyroid gland, respectively. These mass lesions were removed, and the intra-operative parathyroid hormone levels monitored, to confirm the complete resection. After removing the left cystic mass to the inferior thyroid, the serum calcium and immunoreactive parathyroid hormone levels quickly returned to normal. We report a case of primary hyperparathyroidism, caused by a cystic parathyroid adenoma, with a brief review of the literature

AbstractAbstract PDF
Congenital adrenal hyperplasia refers to a group of autosomal recessive disorders that is defective in the synthesis of cortisol. The enzymes most often affected are 21-hydroxylase and 11beta hydroxylase. The low levels of cortisol stimulate the pituitary gland to release ACTH. Chronic elevation of the ACTH level causes bilateral adrenal hyperplasia and a secondary increase in androgen formation. We examined a 19 year-old woman presented with clitoral hypertrophy and vaginal spotting. The subjects basal level of serum cortisol was low, but the serum levels of ACTH, 17a-hydroxyprogesterone, deoxy-corticosterone were elevated. The urinary excretions of 17-ketosteroids and 17-hydroxycorticosteroids were also increased. The karyotyping study and transrectal ultrasonography showed normal findings. The patient underwent clitoris reduction surgery and received hydrocortisone. To the best of our knowledge, this is the first case of 11beta-Hydroxylase deficiency in Korea.

AbstractAbstract PDF
Multiple endocrine neoplasia 2A (MEN 2A) is an autosomal dominantly inherited disease, composed of medullary thyroid carcinoma, pheochromocytoma and hyperparathyroidism. The activation of germ-line mutations in the RET proto-oncogene are responsible for MEN 2. The analysis of the RET mutations has replaced the measurement of the calcitonin level in the diagnosis of the MEN carrier state. Specific RET codon mutations correlate with the MEN 2 syndromic variant, the age at onset of the medullary thyroid carcinoma (MTC) and the aggressiveness of the MTC. Herein, our experience of a 47-year-old woman, who had a bilateral pheochromocytoma and MTC, and MEN 2A confirmed by the detection of an RET proto-oncogene mutation at axon 10 on codon 618, is reported. Her sister was found to have the same mutant gene. After a total thyroidectomy and bilateral adrenalectomy, the calcitonin and catecholamine levels were normalized, and the patient discharged without problems. This case is reported, with a review of the literature.

BACKGROUND
Pheochromocytoma may arise within the adrenal medulla, or in other locations where sympathetic ganglia or chromaffin tissues are known to exist. Approximately 0.1% of hypertensive patients have pheochromocytoma. Most of this hypertension can be cured by surgical removal of the tumor, but lethal complication can develop if proper treatment is not prepared. Therefore, accurate diagnosis and preoperative preparation is very important. The objective of this study was to evaluate the clinical characteristics of pheochromocytoma and the blood pressure change following tumor removal. METHOD: The medical records of 45 patients [29 cases of intra-adrenal, 16 cases of extra-adrenal (paraganglioma)] diagnosed with of pheochromocytoma at Korea University Medical Center between 1991 and 2001 were reviewed. RESULTS: Twenty of the cases were male and 25 were female. The mean age of these patients was 43 years old. Hypertension, headaches, palpitations and impaired glucose tolerance were observed more frequently in cases of intra-adrenal tumor than in those of extra-adrenal. In the extra-adrenal group, abdominal pain, hypertension and nausea were more frequently observed. A biochemical study showed that the sensitivity of the test for catecholamines and metabolites in 24 hours urine was over 80%. For the localization of tumors we used abdominal CT and MIBG. The sensitivities of the CT and MIBG for the tumor localization were 97 and 91%, respectively. Blood pressures during the operations were effectively controlled by preoperative treatment with phenoxybenzamine (non-competitive, non-selective -adrenoreceptor antagonists). CONCLUSION: Surgical treatment cured 23 of the 30 cases of hypertension with pheochromocytoma. We have to take careful approaches in the care of the patient who may have pheochromocytoma, due to the various clinical signs and symptoms.

AbstractAbstract PDF
Papillary thyroid carcinomas comprise approximately 80 percent of all thyroid cancers, but haves a good prognosis, with overall survival rates at 10 years of about 80 to 95 percent. They spreads through the lymphatic system, and the lung is the most frequent metastasis site. If distant metastasis is present, the overall survival rate is about 40 percent. Although malignant pleural effusion, with pleural metastasis is a rare complication in patients with papillary thyroid carcinoma, the development of malignant pleural effusion is an extremely adverse prognostic indicator. We recently experienced a case of malignant pleural effusion with papillary thyroid carcinoma. A 54-year-old woman was admitted to the hospital because of dyspnea. A chest X-ray showed massive pleural effusion in the right hemithorax. Previously total thyroidectomy, and iodine-131 therapy had been performed, but a local recurrence and pulmonary metastasis developed 5 years later, accompanied by malignant pleural effusion with pleural metastasis. We performed diagnostic thoracentesis, which confirmed a metastatic papillary thyroid carcinoma. This patient was a rare case of paplillary thyroid carcinoma, in which the disease was represented by a rapid deterioration with malignant pleural effusion. So we report this case with a review of the literature.

AbstractAbstract PDF
BACKGROUND
Metabolic syndrome (MS) is characterized by insulin resistance accompanied by one or more of the following: obesity, hypertension, impaired glucose tolerance, low HDL cholesterol levels, and/or hypertriglyceridemia. However, the precise underlying pathogenic mechanism of MS is not known. Several recent reports have suggested a positive association between components of MS and markers of the acute-phase response, including C-reactive protein (CRP). These results imply that MS is accompanied by an ongoing inflammatory process. The purpose of our study was to evaluate the association between circulating levels of C-reactive protein, a sensitive systemic marker of inflammation, with components of metabolic syndrome in Korean adults. METHODS: A total of 1,461 subjects aged between 20 and 81 years, who visited the Health Management Center at Korea university between November 2000 and February 2001 were studied. We investigated the correlation between CRP levels and components of MS. The components of MS were categorized, and age-sex adjusted mean values of CRP calculated for the categorized components. The BMI was categorized into 5 classes, and the CRP levels examined according to their BMI class. In addition, subjects with a different number of the MS components were grouped as follows: group 1 for 0 components, group 2 for 1 components, group 3 for 2 components and group 4 for > or = 3 components, and the CRP levels calculated for each group. RESULTS: There were significant positive correlations of CRP levels with age, BMI, TG, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBS), uric acid, insulin,and homeostasis model assessment IR (HOMAIR). A significant inverse correlation was observed between CRP levels and serum HDL. From the multivariate analysis, age and BMI were significantly correlated with CRP levels. The means of the CRP for the categorized components of MS were significantly higher in the BMI categories: > or =25 for female/27 for male, TG > or =200 mg/dL, fasting plasma glucose > or =126 mg/dL and blood pressure > or =140/90 mmHg, and the CRP levels by BMI class were: 1.19 (BMI <18.5), 1.54 (BMI 18.5~22.9), 1.59 (BMI 23.0~24.9), 1.77 (BMI 25.0~29.9) and 2.07 (BMI >30.0) mg/L. Furthermore, the increase in the CRP levels in relation to the numbers of MS were 1.46 (group 1), 1.70 (group 2), 1.95 (group 3) and 2.11 mg/L (group 4) with statistical significance. CONCLUSION: The above data showed associations between the CRP levels and the different components of MS. This might suggest that MS in Koreans could be accompanied by a systemic inflammation response
